-LRB- CNN -RRB- -- The slayings of two super-yacht staff within two weeks have shaken the luxury yacht industry and sparked calls for crews to exercise extreme caution .

Australian luxury yacht captain Drew Gollan was killed in January in English Harbor , Antigua .

Both slayings occurred in popular yachting destinations in the Caribbean and involved violent attacks .

Last week , U.S. luxury yacht chef Sara Kuszak , of Savannah , Georgia , was killed after being abducted during a morning run in Puerto Rico . The body of Kuszak , who was five months pregnant , was found with a slashed throat in a field . A local man has been arrested by police in connection with the incident .

On January 22 , Australian Drew Gollan , captain of Perini Navi yacht Perseus , was shot dead in what was described as a `` failed robbery '' in English Harbor , Antigua .

Gollan , 38 , was described as a `` widely respected member of the yachting community . '' His death came less than a year after the double killing of a British couple on the island . Suspects have been arrested and charged with murder in both cases .

Antigua , in particular , is highly dependent on the luxury yacht industry to boost its local economy -- and it appears news of the crimes is already having a negative impact .

In a press release , the Antigua Charter Yacht Meeting acknowledged that `` a number of boats have decided to leave Antigua in the wake of this incident . '' Further reports from yachting magazine SuperYachtWorld suggest several captains on the island have also decided to leave .

Meanwhile , luxury yacht staff who are remaining in the Caribbean have been urged by industry Web site yotcru.com to `` exercise vigilant personal safety at all times . ''

After the death of Gollan , local Antigua politicians and yacht industry representatives held an emergency meeting to discuss the problem .

At the meeting , the prime minister of Antigua and Barbuda , Baldwin Spencer , said : `` Antigua is still a safe place to be . It 's an unfortunate situation , however we are all hoping that justice will be done , '' SuperYachtWorld reported .

Spencer also pledged new security efforts to help prevent future crimes .

An international charter company manager and luxury yacht industry expert , Els Bucknell , said yacht crews and clients were `` shocked and saddened '' by the deaths , and there would likely be a short-term impact on the Caribbean region .

`` Most people assumed that this part of Antigua was safe and I think it has come as a shock , '' she said . `` Some boats have already left and I think you will see some of that . ''

However , Bucknell felt the incident would not affect the region in the long term .

`` People do forget about these things over time ... and the local business people with police and other authorities have made a serious attempt to make it safer .

`` The economy being the way it is has more to do with how business operates than these kind of things , '' she said .
